Its calibration and errors are discussed. Typical results are presented for the system operation in an Ar/H2(5 % H2) plasma arc jet under a reactor chamber pressure of 101.3 kPa. The plasma temperature and velocity profiles are measured. The center temperature and velocity are 6600 K and 850 m/s for plasma power 9 kW at axial location of 17 mm.展开更多

The new methods aiming at the pilot plant scale are described and the experiments in a small-scale research facility for demonstration and test are presented. The energy consumption for treating waste liquid is 1 kg/kWh. Plasma processing can reduce the costs for treatment and eliminate pollution.展开更多
